"To all wkom it may concern:

' Beit-known"thatLiHIRAM C. ANDERsoN,

'afcitiz en ofthe'Un'ited States, and a resident of the c'ity of New York, 'Westchester, borough ofithe Bronx, in the county of "Bronx and State of New "York, have invented a new and Improved Resilient Wheel,

eiract description.

This invention relates to resilient wheels offthe character covered by Letters vPatent of the United" States No. 1,239,333, issued to me on 'the' 4th day of} September, 1917; and

has toritsobjects'thej formation of a wheel of averyicompact'simple and reliable nature and one which" possesses all of the resilient qualities of a wheel having a pneumatic'tire.

f vide, whatis the equivalent of a pneumatic hub'dt'or a iw'heel whereby the pneumatic Another: object of the invention isto procushioning mean'sare so placed and guarded as to .be practically indestructlble in so far as traction or' contact with the ground are I; concerned.

fjVYiththe foregoing and'other objects in viewfthe'invention consists in the arrange- I .mentand combination of parts hereinafter descr bed and c l'a'1med,' and while the inven- 'tion is notrestricted to'the exact details of construction disclosed or suggested herein,

'stillior the purpose of'illustrating a practi- 'cal e'mbo'diment thereo'freference is had to {the accompanying drawings, in which like reference" oharacters'fdesignate the same parts in the several'views, and in which' "Figure 1 is a. side'eleva'tion of my im-f provedwheel looking outward'fromthe vehiclbody with parts broken away to show ther esilient locking lugs and the valve'stem.

@Fig. 2is an' 'enlargedvertical section on" the line 22 of Fig.1. i p I Fig-3. is a partial elevation and partial section onthe linej3'3 of 'Fig. 2 indicating the line 4-4 ofFig. 1; and I 4 .;;Fig.-,5 is-a. detail plan view of a port on of ,the'innerj hub member.

-' special means for limiting-the extent of relativel rotation between the inner and outer. hub "members.

4 is a' transverse sectional detail on Referring now more specifically to the drawings I show a wheel comprising a sleeve 1O fixed on-fitted in any suitablemanner {a es a1 spindle or axle llfas by means of a, key 12 and held from'slippin'g therefrom by ff'which" the following isa full, clear, and

and removably -tion s 20 a 5 'meansofanut-13 and cotter 14, the hold- 111g means being housed within a cap nut 15 screwed onthe sleeve. The end of the sleeve remote from fthe cap "15 carries a-disk or plate 16 which may carry a brake hub 17 orother means for controlling the rotation of the wheel.

The hub structure prises an inner mating parts 18 above referredto com- 7 portion 7 consisting of two and 19'fitted upon the sleeve connected together by any suitable} means such aspin and slot 'connecthe pins beingshown as car- IIQCl by the member '18 and the slots being formed-ln-the member 19 wherebyone part -may bejremoved from the other by giving first-a slightrotation theretojand then a movement parallel to the axis of the shaft or axle 11. The outer face portions of the 2 members 18 and*19 constitute a concave seat "22 and the side faces of these hub members are flat and parallel to each other.

The outer hub member comprises a disk member 23'on one side of the wheel and on the opposite side aretwo disk members 24 and 25 adapted to be'rigidly secured to the first mentioned disk member 23 by means of faces of the inner hub members and over 7 "whichthe'y are adapted to lie both circumferentially-and radially with respect to the axis of the wheel within suchlimits as are 1 essential for the desired resiliency of the structure in practice. Thedisk' member 23 is provided with radial sockets 31 having the appearance of spokes. These sockets are substantially cylindrical and are so formed that their axes all lie in the central plane of the wheel while the main portion of the disk carrying such socket members ha's'contact with the members 24' and 25 in aplane spaced laterally from the central 5 plane the socket members I The inwardly; projecting ring of the member 23 is provided witha'large central opening 32 "spaced outward radially" aforesaid .a distance equal to th'e' radius of ortion '29 from the 'abutnientineinber 33 carried by V the plate 16 and through which abutment member the inner hub member 19 is secured by any suitable means/such as bolts 34 having lock nuts 35. 'Likewise the opposite annulus 30 has a large central opening 36 spaced outward radially from the abutment member 37 formed on or secured to a face plate 38 fitted upon the end of'the sleeve 10 adjacent to the cap and substantially of I t-hesame size and form as the plate 16. v The lastmentioned plate 38 and its abutment extension 37 are secured to the inner hub at 18 by bolts-39 having lock nuts 40.

The peripheries of the members 23 and are bent away from each other forming shoulders 41 and 42, thence outward radially fromthe'shoulders forming side flanges 43 and 44 for the purpose of securely looking a suitably formed cushion tire 47, or its equiv- 'alent, against thering shaped rim 48 supported upon or and 42. Access may be hadto the mm 48 I and ,the tire for removal or interchange 25"thereof by separating the member 25from f formed preferably of a good quality of rubagainst said shoulders 41 the disk member 23 by loosening the bolts 25.; Even though the plane'of connection between the rim members is offset from the center at the central plane of the wheel am-' ,ple strength and stiffness are afforded by the socket'structures 31 in addition to the main portions of the disks.

i The pneumatic cushioning means includes an annular shoe 49 having formed upon its eri her. an annular series of lu s 50 P P 1 2:

her. The inner portion of the shoe or that portion remote fromthe lugs 50 comprises two overlapping portions 51, the extreme edge'of each of which portions is quite o thin and terminates in a circumference equal a the outer seat 28 with the lugs projecting to the center line of theshoe. These overlapping portions of the shoe are adapted to seat in the inner hub member seat 22 while the outer portion -,of the shoe bears against into and fitting snugly in the sockets 31.

Because of the snug fit'of the lugs50 in their meansas "a whole tends to maintain the inner to relative circumferential satisfactory operation of the wheel than would be possible'if there were looseness between the lugs :o and the socket walls, \Vithin the shoe is an inflatable member or i inner tire 52 having a filling nozzle 53 prov jecting outward through a slot 54 formed in .mem-ber-2 3.

the shoulder portion 26 of the disk In assembling the wheel theldisk 23 is slipped into place against the plate 16 and the inner hub'member 1-9v is then put in place and lockedby means of the bolts 34. The

limited and consequently the flange 29.

cushioningdevices are then inserted bring ing the lugs 50 into the sockets 31 and then; the other inner hub member 18 is slipped upon the sleeve'lO bringing the overlapping portions of the inner members into registryvoi 1 and then the member 18 is given a slight rotation to cause the interlocking through.

the bayonet slot connections 20' and21. The

disk member 24isthen put in place over the cushioning devices and the member 18 and secured through the. bolts 24 to the disk member 23 1 The face plate 38 is put into? place and looked as above described, and

finally the cap 15 is put upon the outer end' of the sleeve. 'By reason of the detachable connecting devices 24 and 25 securing the disk parts'24'and 25 independently of each I other to the disk 23 either member 24 or 25 7 may be detached from the disk 23 without disturbing the connections of the other part.

In other words a new tire may be introduced by simply removing the disk member 25',

the hub or cushioning members remaining 7 undisturbedor while the tread portions 10f o the wheel remain undisturbed the shoe '90 and parts associated therewith may be inspected, renewed or interchanged upon re moving the parts 24,18 and 38. 1 l

In the foregoing assembly of the wheel it ispreferred that the. hub and disk portions shall be so positioned with-respect toone another and the hub sleeve that the pe riphery of the wheel may be caused to rotate to a certain extent in either direction while the said sleeve and parts connected thereto may remain stationary. It is desirable, however, that vthe extent of such rotation be I provide the features shown and now to be described.

The plate 16 is recessed on its inner face as shown at 55', the recess being directedfrom the periphery of the plate 16 inward radially to a shoulder 56 and bounded circumferentially by radial faces or shoulders 57 The annular flange portion 29 of the disk 11 0 23 is provided adjacent to the face plate 16 with a suitable projection.58 whichextends into the recess 55. The luglor projection 58 maybe made in any suitable manner but is indicated as being punched outward from the planeof the annulus 2 9 by a .swaging tool so asto constitute an integral .part of tween the tread portions of the wheel-and the hub portions, and after the parts have been assembled as above described 'with the lug 58 substantially central between the shoulders 57 the resiliency ofthe cushioning members will tend to maintain the wheel in such relation. The lug {58 may be said furthermore to have free floating action in" or along any portion of the recess 55 so far As )IlLY-bBLi'GitdllY. appre- V ,ciated from Figsy2 and 3 the'lug 58 in its cooperation with eitherof the shoulders 57 120 'will limit the extent of relative rotation beas permitted bythe resiliency of the cushioning devices and their tendency to hold the lug central.

I claim:

In a resilient wheel, the combination of inner hub means, resilient cushioning means carried by the inner hub means and including a series of radially projecting lugs of cylindrical form and outer hub means cooperating with the resillent cushionlng means and comprising two disk members lying in the same plane at one sideof the cen the cushloning means, another centers lie in said central plane of the cushloning means, and means to secure sa d disk members together. 7
